    Advice

    After calculating a creatinine clearance, providers should consider calculating an actual GFR as well, to determine the staging/severity of a patient's chronic kidney disease.

    CKD stage GFR level (mL/min/1.73 m2)
    Stage 1 ≥ 90
    Stage 2 60 – 89
    Stage 3 30 – 59
    Stage 4 15 – 29
    Stage 5 < 15
